Connections
The Qualistar models are ideal for applications on all types
of electrical networks, from the simplest to the most complex:
• Single-phase, split-phase and three-phase with
or without neutral
• All types of 2, 3, 4 and 5-wire electrical networks
• 2-wattmeters method
• ARON
• 2 ½ elements…
Longer Inrush…
over 10 minutes!
The Inrush current corresponds to the
maximum input current drawn by an
electrical device when it is powered up.
This measurement helps to size the
electrical installation correctly.
The Inrush is measured over
a period of 10 minutes.
Once you have chosen
the acquisition mode (RMS or
peak), the Qualistar captures
everything.
Short or long-term icker
The icker (as dened by the IEC/EN
standard) characterizes voltage variations
which cause lighting uctuations, for
example.
According to the applicable standards, the Flicker level is expressed by
two parameters:
• Pst ( short-term icker)
Calculation of the Pst, which is used to assess the icker level,
is based on statistical processing of the voltage signal sampled.
It is measured over a period of 10 minutes
• Plt (long-term icker)
This is a multiple of the Pst. It is measured over a period of 2 hours.
